I'm surprised that Bertram is so simplistic in his view about why his business is failing.
Would his business viability have anything to do with;
- rising price of consumables like fuel, oil, office equipment, etc
- rising cost of maintenance and engineering
- rising cost of insurance
- rising cost of maintaining documents and licences due to government regulations
- increasing cost of living, and the fact he is providing a service to customers who may spend money on other priorities when finances are tight?
Nah! Nothun to do wit dat!
